Ok it might not be that bad...seems there was terrible info relay and that they were talking about the ps5 boost mode only supporting 100 games, the legacy mode should play all ps4 games...
But hot damn this is a mess, twitter nikkas, IGN all reporting it wrong. What a shyt show this was
Your PS5 will load into a legacy PS4 mode to play the old games supposedly. I dont know if that is true but comparable to Xbox 360 game to Xbox One
